[0032] After the reaction is completed, hot water is added into the reaction kettle 1 through the hot water pipeline 4, and after the hydrolysis is stirred, the valve on the discharge pipe 10 is opened, and then the reaction liquid can be discharged through the discharge pipe 10, the outer wall of the reaction kettle 1 is provided with an electric heating plate (not shown in the figure), which is used to heat the reaction liquid in the reaction kettle 1, the reaction liquid enters the reaction kettle 1 through the feed pipe 9, and the use is simple and convenient
[0033] As Figure 2 The driving member includes an inner ring gear 12 and a circular groove 13 coaxially arranged on the disc 2, the inner ring gear 12 is coaxially located in the circular groove 13, and the outer wall of the inner ring gear 12 is fixedly connected with the groove wall of the circular groove 13, one side of the outer wall of the reaction kettle 1 is provided with a motor 14, and one end of the rotating shaft of the motor 14 penetrates through the kettle wall of the reaction kettle 1 and is provided with a gear 15, the gear 15 is located in the inner ring gear 12 and is engaged with the inner ring gear 12, the purpose of this setting is that when it is needed to drive the disc 2 to rotate, the motor 14 is only needed to be turned on, at this time, the rotating shaft of the motor 14 will drive the gear 15 to rotate, at this time, the gear 15 can drive the disc 2 to rotate through the inner ring gear 12 engaged therewith, and the use is simple and convenient.
[0034] As Figure 2 and Figure 4The inner wall of the reaction kettle 1 is rotatably connected with a support ring 16 opposite to the disc 2, and the end of each connecting plate 7 away from the disc 2 is fixedly connected with the support ring 16. When the disc 2 drives each connecting plate 7 to rotate along the rotation axis of the disc 2, the support ring 16 rotates with the disc 2 through each connecting plate 7. At this time, the support ring 16 can provide support force for the end of each connecting plate 7 away from the disc 2, reducing the bending of the connecting plate 7, and the use is simple and convenient.
[0035] As Figure 2 and Figure 3 The reaction kettle 1 is provided with a stirring part for stirring the reaction liquid in the reaction kettle 1. When the gear 15 rotates, the gear 15 drives the stirring part to stir the reaction liquid in the reaction kettle 1. The stirring part includes a stirring shaft 17 rotatably connected to one side of the inner wall of the reaction kettle 1. The stirring shaft 17 is horizontally arranged and opposite to the gear 15. At this time, one end of the stirring shaft 17 is located in the support ring 16. The end of the stirring shaft 17 close to the gear 15 is coaxially fixedly connected with the gear 15. The stirring shaft 17 is provided with a plurality of stirring rods 18. The dispersion pipe 5 is located below the disc 2 and the support ring 16 and is parallel to the stirring shaft 17. When the gear 15 rotates, the stirring shaft 17 rotates with the gear 15. At this time, the reaction liquid in the reaction kettle 1 can be further stirred by the stirring rods 18 on the stirring shaft 17. At this time, because the gear 15 drives the disc 2 to rotate through the inner gear ring 12 engaged with it, the rotation speed of the stirring shaft 17 is greater than that of the disc 2.
[0036] Because the dispersion pipe 5 is located below the disc 2 and the support ring 16 and is parallel to the stirring shaft 17, when the nozzle 6 on the dispersion pipe 5 sprays isobutene gas into the reaction liquid for reaction, the isobutene gas bubbles moving upward will enter between the disc 2 and the support ring 16. At this time, the reaction liquid in the reaction kettle 1 can be stirred by the stirring rods 18 on the stirring shaft 17, which facilitates the reaction of isobutene gas and reaction liquid, and the use is simple and convenient.
[0037] As Figure 2 and Figure 3The relative two sides of the inner wall of the reaction kettle 1 are vertically and slidably connected with sliding plates 19, the disc 2 and the supporting ring 16 are respectively rotationally connected on the two sliding plates 19, the reaction kettle 1 is provided with a driving part for driving the two sliding plates 19 to vertically move up and down, the two sliding plates 19 are vertically provided with communication grooves 20, one end of the rotating shaft of the motor 14 provided with the gear 15 passes through one of the communication grooves 20, one end of the stirring shaft 17 passes through the other communication groove 20, the gear 15 is located below the inner ring gear 12, the purpose of the setting is that the two sliding plates 19 are driven by the driving part to vertically move down, at this time, the supporting ring 16 and the disc 2 will respectively move down with the two sliding plates 19, at this time, because one end of the rotating shaft of the motor 14 provided with the gear 15 passes through one of the communication grooves 20, one end of the stirring shaft 17 passes through the other communication groove 20, so the positions of the gear 15 and the stirring shaft 17 in the reaction kettle 1 remain unchanged, with the vertical downward movement of the two sliding plates 19, the meshing state of the inner ring gear 12 on the disc 2 and the gear 15 will be disconnected, then the driving part continues to drive the two sliding plates 19 to vertically move down, and the motor 14 is turned off, until the gear 15 meshes with the inner ring gear 12 again, at this time, the gear 15 is located above the inner ring gear 12, then the motor 14 is turned on, at this time, the disc 2 can be driven to rotate again by the inner ring gear 12, at this time, the gear 15 and the inner ring gear 12 are disconnected and meshed again by the downward movement of the two sliding plates 19, the height position of the disc 2 and the supporting ring 16 in the reaction kettle 1 can be adjusted, the isobutene gas floating in the reaction kettle 1 can be brought into the reaction liquid, the disc 2 always rotates in one direction, and the top end of the disc 2 always locates outside the reaction liquid;
[0038] When the reaction of the isobutene gas and the reaction liquid is finished, the two sliding plates 19 can be vertically moved by the driving part, so that the meshing state of the inner ring gear 12 and the gear 15 is disconnected, after the meshing state of the inner ring gear 12 and the gear 15 is disconnected, the driving part stops working, at this time, the disc 2 will not be driven to rotate by the inner ring gear 12, but the gear 15 continues to drive the stirring shaft 17 to rotate to continue stirring the reaction liquid after the hot water is added by the stirring rods 18, at this time, the load of the motor 14 driving the gear 15 to rotate can be reduced, which is simple and convenient to use.
[0039] As Figure 2The driving member comprises a screw rod 21, an inverted U-shaped fixed plate 22, and a transmission rod 23 coaxially arranged on the screw rod 21. The top ends of the two sliding plates 19 are connected through the fixed plate 22. The screw rod 21 is rotationally connected to the top end in the reaction kettle 1. The bottom end of the screw rod 21 penetrates through the fixed plate 22 and is threadedly connected with the fixed plate 22. The transmission rod 23 is arranged at the top end of the screw rod 21. The top end of the transmission rod 23 penetrates through the reaction kettle 1 and is provided with a rotating disc 24 outside the reaction kettle 1. The purpose of the arrangement is that when the two sliding plates 19 need to be vertically moved, the rotating disc 24 only needs to be rotated. At this time, the rotating disc 24 drives the screw rod 21 to rotate through the transmission rod 23. At this time, because the bottom end of the screw rod 21 penetrates through the fixed plate 22 and is threadedly connected with the fixed plate 22, and the top ends of the two sliding plates 19 are connected through the fixed plate 22, when the screw rod 21 rotates, the fixed plate 22 can be pushed to vertically move the two sliding plates 19. The use is simple and convenient.
[0040] As Figure 2 and Figure 4 A plurality of disturbance plates 25 are arranged on each connecting plate 7 along the length direction of the connecting plate 7. When the disc 2 drives each connecting plate 7 to rotate along the rotation axis of the disc 2, the stirring effect of the connecting plate 7 on the reaction liquid can be increased through each disturbance plate 25 on each connecting plate 7. The use is simple and convenient.
[0041] In example 2, the reaction liquid in the reaction kettle 1 is located at the upper middle side of the disc 2. When the isobutene gas is introduced into the dispersion pipe 5 through the gas inlet pipe 3 and the disc 2 is driven to rotate by the driving member, the isobutene gas is sprayed into the reaction liquid in the reaction kettle 1 through each nozzle 6 on the dispersion pipe 5 to react. When the disc 2 rotates, the disc 2 drives each connecting plate 7 to rotate along the rotation axis of the disc 2. At this time, because the water level of the reaction liquid is located at the upper middle side of the disc 2, part of the connecting plates 7 on the disc 2 is located outside the reaction liquid, and the remaining connecting plates 7 are located inside the reaction liquid. When the disc 2 drives each connecting plate 7 to rotate along the rotation axis of the disc 2, one side of the connecting plate 7 located outside the reaction liquid, which is provided with the groove 8, is first in contact with the reaction liquid with the rotation of the disc 2, and then the connecting plate 7 rotates into the reaction liquid with the rotation of the disc 2. At this time, when the isobutene gas overflows from the reaction liquid and floats in the reaction kettle 1, the isobutene gas floating in the reaction kettle 1 can be brought into the reaction liquid again to participate in the reaction through the groove 8 on the connecting plate 7 located outside the reaction liquid and rotating with the disc 2. At the same time, the reaction liquid in the reaction kettle 1 can be stirred through each connecting plate 7 on the disc 2.
[0042] After the reaction is completed, hot water is added into the reaction kettle 1 through the hot water pipeline 4. After the hydrolysis is stirred, the valve on the discharge pipe 10 is opened, and the reaction liquid can be discharged through the discharge pipe 10.
[0043] Obviously, many modifications and variations of the present application are possible in light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims and their equivalents, the application can be practiced otherwise than as specifically described.

Because the reaction liquid level is located in the upper middle part of one side of the disc (2), some of the connecting plates (7) on the disc (2) are located outside the reaction liquid, and the remaining connecting plates (7) are located inside the reaction liquid. The disc (2) drives the connecting plates to rotate along the rotation axis of the disc (2). When the connecting plate (7) rotates along the rotation axis of the disk (2), the side of the connecting plate (7) with the groove (8) located outside the reaction liquid will first come into contact with the reaction liquid as the disk (2) rotates. Then the connecting plate (7) rotates into the reaction liquid as the disk (2) rotates. When the isobutylene gas overflows from the reaction liquid and floats in the reactor (1), it is brought into the reaction liquid again by the groove (8) on the connecting plate (7) that follows the rotation of the disk (2) and is located outside the reaction liquid. At the same time, the reaction liquid in the reactor (1) is stirred by the connecting plates (7) on the disk (2). After the reaction is complete, hot water is added to the reactor (1) through the hot water pipeline (4). After stirring and hydrolyzing, the valve on the discharge pipe (10) is opened and the contents are discharged through the discharge pipe (10).
